ANTISKIDDING DEVICE FOR'MO'IOR-VEHICLES.

Specification of Letters Patent.

Patented July 20, 1915.

Application filed March 20,1915. Serial No. 15,915.

' To all whom it may concern:

Be it known that I, WILLIAM NORTON, a citizen of the United States,residing at San Francisco, in the county of San Francisco,

and State of California, have invented certain new and useful.Improvements in Antiskidding Devices for Motor-Vehicles, of

which the following is a specification, reference being had to theaccompanying drawmg. I

This invention relates to an improved anti-skidding devicefo'r-motorvehicles, and v has for its primary object to provide a very simple andeffective device for this purpose, whereby sidewise skidding or slidingmovement of the vehicle upon treacherous road surfaces may be prevented.

The invention has for an additional object to provide an anti-skiddingdevice for vehicles embodying a vertically movable part mounted upon thevehicle frame and provided on its lower end with a road engaging shoe,and manually operable means for lowering or raising said part to disposethe shoe in effective engagement with the road surface or in an elevatedinoperative position.

It is a further general object of the invention to produce a device ofthe above character which is strong and durable in its con struction,inexpensive to manufacture and readily applicable to the vehicle withoutnecessitating any changes in its construction, and is highly convenlentand serviceable for the purposes in view.

With the above and other objects in view,

my invention consists in the novel features of construction,combination, and arrangementof parts to be hereinafter more fullydescribed, claimed, and illustrated in the accompanying drawing, inwhich,

Figure 1 is a side elevation showing the present invention applied to amotor vehicle frame, the shoe being illustrated in its lowered positionin dotted lines; Fig. 2 is a top plan view; Fig. 3 is a section taken onthe line 33 of Fig. 1;-and Fig. 4 is a detail perspective view of theshoe.

In the accompanying, drawing, I have shown my invention applied to amotor vehicle frame or chassis 5 which is mounted in any ordinary orapproved manner upon the usual front and rear axles 6 and 7,respectively, upon the ends of which the supporting Wheels 8 arearranged. The frame structure 5 includes spaced intermediate transversebars 9 and the rear tudinal bars 10.

The invention forming the subject matter of the present application,includes a vertically disposed metal'g'uide sleeve or' tube 11 whichextends between and above and below the longitudinal frame bars 10.Intermediate of its ends, this sleeve is provided. with oppositelyextending lugs or ears 12 to be disposed upon the under sides of thelongitudinal bars 10 and secured thereto by suitable bolts .indicated at13. The lower end of the tube 11 is provided with similar ears 14 towhich the lower ends of the inclined parallel longitruss bars 15 arebolted, the other ends of wear awayand leave the centralsteel bar in.

such form as to securely grip the road surface. The shoe is thus, ineffect, self-sharpn I Upon one of the transverse bars 9 of the vehicleframe, a hanger bearing or support 21 is secured by the bolts 22. Thishanger includes a downwardly extended bifurcated I arm 23 and the spacedupwardly extending ears 24 whichare formed upon the upper end of thehanger and are disposed out of vertical alinement with the arm 23. Thelower end of the arm 23 is bifurcated to receive one end of a rod 25which is provided with a longitudinal slot 26 in which a pin 27, fixedin the bifurcated end of the arm 23, is engaged. The other end of therod 25 is pivotally connected, as at 28, to the forward end of the shoe18. In the upwardly projecting ears 24 of the hanger, a lever 29 isfulcrumed adjacent to its lower end. In a bracket member 30 fixed to therear transpivotally pivotally connected. The lower end of thisodis'pivotally connected, asat 3.6, to the I, lower'end'of the,vertically movable rod 16.

' wardly in the. sleeve l1 and lower the shoe 'into'contact with theroadsurface... tudinallyapplliedpressures by means of rod- WhlC Iposition shown in dotted lines in j 'Fromth'e foregoing description, the0 er- 5 follows; Assuming that the parts are in the ati'on of myinvention will be understoo as icy or slippery road surfaces are en coun"red,- the operator shifts the lever to 'the dotted line' position, andthus actuates the bell crank '31 to force the rod downwardly andthusalso slide the rod 16' dow'ii The shoc-is'efl'ectually braced towithstand lon%' is connected to the forward end of the shoe. In thismanner, it will be seen that the anti-skidding shoe may be very easilyand .quickly lowered into engagement with the road surface or elevatedby a reverse movement of the lever to the inoperfa tive position shownin full lines in Fi 1. a It Wlll, course, be obvious that, if desired,

a foot pedal maybe substituted'for the hand lever 29, The mechanism foroperating the "shoe might also be actuated by com ressed in racticaluse. p dihile I have shown and. described-the the several elementsemployed, that the device is susceptible of considerable bodied withinthe spirit invention as claimed. 7

preferred construction and arrangement of it is obvious modificationtherein, and I, therefore, reserve the privilege of resorting to allsuch legitimate changes as may" be fairly emand scope of the I Havingthus fully described my invention, what I desire to claim and secure byLetters Patent is The combination with a motor vehicle including aframe, of a vertically dis osed guide sleeve fixed in said frame, a rovertically slidable in said sleeve,- a longitudinallyextending shoesecured to the lowerend of said rod, a hanger bracket fixed upon themachine frame and having a downwardly extending arm,-'a rod pivotallyconnected to one end of the shoe at its rear end and slidably connectedto the'bracket arm at its other end, an operating lever mounted uponsaid bracket, a bell crank lever fulcrumed in the frame, a rod connectedto one arm of said lever and to the lower end of the vertically slidablerod, and a connecting rod between the other arm of said bell crankand'the lower end of 'the operating lever whereby said shoe may belowered or :ai'sed to its operative or inoperative posi- In testimonywhereof I hereunto aflix my signature in the presence of two witnesses.
